The aim of the present study was to establish a selecting resistant black pepper plants from susceptible germplasm using as selective agent a mixture of toxins produced by the pathogen. The route to this objective is: To establish methods of production of fungal culture, host callus and cell suspension cultures; To study the reaction of the whole plant and callus to pathogen colonization; To investigate the reaction of callus and cell suspension when growing in contact with toxic culture filtrate; To elucidate the role played pathogen-produced toxin in pathogenesis; To purify toxin(s) produced the pathogen; To select resistant sectors from callus of different cultivars through passage in toxic culture medium; To try to regenerate black pepper plants from callus. |
